Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617130, here are decompositions:

29 + 31617101 = 31617130
53 + 31617077 = 31617130
101 + 31617029 = 31617130
107 + 31617023 = 31617130
131 + 31616999 = 31617130
179 + 31616951 = 31617130
197 + 31616933 = 31617130
227 + 31616903 = 31617130

Showing the first eight; more decompositions exist.
